Published by ELSEVIER B.V. This is an open access article under the CC BY-NC-ND license (https://creativecommons.org/licenses/by-nc-nd/4.0) Peer-review under responsibility of ICSI organizers Abstract The demand for advanced pipeline materials has increased in response to the growing need for sustainable, durable, and structurally resilient solutions in the transportation of energy and resources, in particular high-pressurized gaseous hydrogen. Whilst traditional steel pipelines are widely utilised, they are susceptible to hydrogen-induced corrosion, which compromises their structural integrity, efficiency, and lifespan. Fibre-reinforced plastic (FRP) composites present a transformative alternative, offering exceptional resistance to corrosion, enhanced mechanical properties, and adaptability for various pipeline applications. The present study investigates the potential of fibre-reinforced polymer (FRP) composites to replace steel in the construction of hydrogen transport pipelines, with a particular focus on structural integrity in the context of gaseous hydrogen transport. Research conducted at the Institute for Textile Technology (ITA) at RWTH Aachen University addresses crucial aspects of FRP pipeline development with an emphasis on structural performance. The subjects encompassed material characterisation for the purpose of determining hydrogen permeation rates and evaluating barrier properties, in addition to advances in process technology for scalable and efficient production utilising multifilament winding techniques. Moreover, the research evaluates connection technologies to ensure secure and reliable pipeline assembly, as well as life cycle analyses to quantify the environmental and economic benefits of FRP pipelines compared to traditional steel systems.
